Request: Include a Nametag key if the poi has been given a name

[dfeneck]

I have all signs in my world being rendered, it would be nice to be able to exclude some without using a line of text on the sign.

A simple poi['nametag'] if the poi entity has been given a name would suffice for this.
Then players could name a sign 'hidden' and it won't show up!

A humble suggestion anyway,
Cheers.

You can achieve this in your filter function easily enough.

If you simply want to exclude all entities the filter handles that have "any" name then you can simply use:

if 'CustomName' in poi:
  return

If you want to base it on the value of the name then you'll have to expand it to:

if 'CustomName' in poi:
  import json
  namejson = json.loads(poi['CustomName'])
  if 'text' in namejson and namejson['text'] == 'hidden':
    return

Unfortunately I have always found that adding import json to the top of overviewer.conf has been insufficient and I couldn't be bothered to figure out why however this method does work.

@jobe1986
You have to declare this as global
It is on line 74 of docs/signs.rst

Because of the way the config file is loaded, if you need to import a function or module
for use in your filter function, you need to explicitly load it into the global namespace::

    global escape
    from html import escape
    def signFilter(poi):
        if poi['id'] == 'Sign' or poi['id'] == 'minecraft:sign':
            return escape("\n".join([poi['Text1'], poi['Text2'], poi['Text3'], poi['Text4']]))
